Carlos Pardo will give an online presentation about Automotive Optical Multi-gigabit Ethernet at the Automotive Technologies Virtual Conference on May 13, 2021

Carlos Pardo will give an online presentation about Automotive Optical Multi-gigabit Ethernet at the Automotive Technologies Virtual Conference on May 13, 2021 at 5:30 p.m. EST and on demand. In-Vehicle Network (IVN) requirements are quickly evolving with new challenges like automated driving or electric power trains. The IVN has to support use cases such the vehicle data backbone, smart antennas, ADAS cameras/sensors, and displays or data loggers which demand higher data bandwidth while maintaining the reliability level required by the automotive industry. A new IVN standard is needed for multi-gigabit optical communications.

This optical automotive IVN communication standard, 802.3cz, is currently under development within the IEEE and is supported by several industry-leading companies. The new standard will cover rates up to 50 Gbits/s and support several in-line connectors. The target BER is better than 10-12 with ambient operation temp from -40°C up to +105°C (AEC-Q100 grade 2) in harsh automotive environments. High reliability (15 years operation, less than 10 FIT), and outstanding EMC compliance will also be fulfilled. In his presentation, Carlos Pardo will cover the needed standard, and detail the components needed to make this a reality.

Demo: World’s First 50 Gb/s Automotive-grade Optical Network

KDPOF has successfully participated at the virtual ISCAS 2020 in October with several contributions: a presentation on multi-gigabit Ethernet for the automotive industry, an overview lecture on high-speed data communications over POF, and an important role in the final industry panel session. The IEEE International Symposium on Circuits and Systems (ISCAS) is the flagship conference of the IEEE Circuits and Systems (CAS) Society and the world’s premiere networking forum for researchers in the highly active fields of theory, design, and implementation of circuits and systems.

Towards the Multi-Gigabit Ethernet for the Automotive Industry

Session Chairmen Enrique Prefasi Sen, Analog and Mixed Signal Senior Designer of KDPOF, and Alberto Rodríguez-Pérez, Analog and Mixed Signal Manager of KDPOF, have presented the paper “Towards the Multi-Gigabit Ethernet for the Automotive Industry”. The paper, within the special session “Multi-gigabit Wireline & Optical Communication Circuits & Systems Session”, showed the status of Ethernet-based communication solutions, focused on optical links for the automotive industry. They displayed the implementation of a product compatible with the 1000BASE-RHC according to the IEEE Std 802.3bv, which is the first one able to transmit 1 Gbps over POF for automotive. In addition, the KDPOF experts described a new architecture to achieve up to 25 Gbps for automotive. The proposed multi-gigabit system leverages existing technologies such as VCSELs, multi-mode fibers, and photodiodes already developed for the data center industry.

High-Speed Data Communications over Fiber Optics

In his lecture, Alberto Rodríguez-Pérez gave an overview of the use of Plastic Optical Fiber as a medium for optical data communications and the techniques needed to get high speed data bitrates over POF. It is an interesting alternative optical communication channel to the Glass Optical Fibers (GOF) for applications that are not required to cover long distances, such as home or automotive networking. However, the reduced low bandwidth of the POF channel imposes big limitations in the maximum data bitrate that can be transmitted through this medium. Consequently, advanced data communication techniques such as channel equalization, data error correction, or data signal modulation need to be applied to achieve data bitrates above 1 Gbps.

Photonics Days Berlin Brandenburg: Optical Automotive Ethernet Presentation

KDPOF is delighted to present at the virtual Photonics Days Berlin Brandenburg 2020 from October 5 to 8, 2020. On Monday, October 5 at 10:40, César Esteban, Application and Support Manager of KDPOF, will give the presentation “Optical Automotive Ethernet” within the session “Innovative Optical Fibers”. Plastic optical fibers (POF) are the most reliable solution in vehicles since they can withstand harsh environments, vibrations, misalignments, dirtiness, humidity, wide temperature range, etc. Additionally, optical Ethernet generates very low noise and can operate in noisy environments, such as in RF electronic boards.

Full Standardization of Optical Gigabit

Recently, ISO (International Organization for Standardization) has added two new sections to the in-vehicle Ethernet series 21111. These newly approved parts are key components to assure reliable implementations of systems that realize in-vehicle Ethernet Optical 1 Gb/s as a physical layer. With the new ISO 21111 sections complementing the existing IEEE Std 802.3bvTM, optical Gigabit connectivity is now entirely standardized. Based on these standards, KDPOF’s optical technology allows a complete, compatible, and interoperating implementation for carmakers and Tier1s.

The KD1053 transceiver perfectly meets the requirements of carmakers by providing high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver is optimized for low power and small footprint and transmits data at 1000/100 Mb/s on standard SI-POF, MC-POF, or PCS, according to 1000BASE-RH (IEEE 802.3bv).

Outlook on Optical Multi-Gigabit

With technological leaps such as electrical vehicles, automated driving, and V2X interconnection rushing through, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously. Consequently, in-vehicle networks are on the brink of speeds from one to multiple gigabits per second. Optical Multi-Gigabit Ethernet in the car is on the verge of standardization and implementation. With the approval of the IEEE 802.3 working group, a team of individuals affiliated with more than 15 key carmakers and components suppliers, including KDPOF, has started the standardization of an IEEE 802.3 Automotive Optical Multi-Gigabit Standard with strong support from the industry. KDPOF has already displayed the world’s first demonstration of an automotive-grade optical transmission system with 50 gigabits per second single lane, leveraging datacom components.

At the virtual WEKA Bordnetz-Kongress 2020 (Wire Harness Congress) on September 22, 2020, KDPOF displayed insights and update on Optical Multi-Gigabit Connectivity. Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, presented how automotive networks profit from optical technology. Electric and autonomous driving architectures are substantially pushing the challenges for wiring systems. Issues include electromagnetic interference (EMI), electromagnetic susceptibility (EMS), and weight reduction. On top, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously. The new 48-volt electrical architecture in cars additionally pushes the envelope in terms of cross-domain isolation requirements. Copper links for communication rates above 100 Mb/s need heavy and expensive solutions to comply with the stringent OEM’s EMC specs, resulting in high cost and very difficult engineering. Moreover, the weight of the ever-growing diameter of the required cables plays against the race for range increase of electrical powertrains.

Optical network technology overcomes these trends thanks to its inherent galvanic isolation, robustness, low cost, and low weight. Carmakers will benefit from optical links for communications between the 48-volt and the 12-volt domains. For weight, the optical network will save more than 30 percent of the equivalent copper-based harness weight. Optical Ethernet provides 100 Mb/s and 1 Gb/s network solutions today, and multi-gigabit Ethernet is the significant upcoming breakthrough for in-vehicle networks. The standardization effort for optical multi-gigabit is already in progress within the IEEE as an amendment to the Ethernet standard 802.3.

KDPOF is looking forward to participating in the upcoming virtual ISCAS 2020 from October 10 to 21 with several contributions: a presentation on multi-gigabit Ethernet for the automotive industry, an overview lecture on high-speed data communications over POF, and an important role in the final industry panel session. The IEEE International Symposium on Circuits and Systems (ISCAS) is the flagship conference of the IEEE Circuits and Systems (CAS) Society and the world’s premiere networking forum for researchers in the highly active fields of theory, design, and implementation of circuits and systems.
